Definitions

  • the invention relates to a hard tile having a support layer and a wearing layer and to a covering surface comprising such tiles.
  • a hard tile having a support layer and a wearing layer and to a covering surface comprising such tiles.
  • very high demands in terms of mechanical strength, resistance to wear and resistance to chemicals are imposed on covering surfaces made from plastics.
  • such coverings should not undergo any electrostatic charging or should at most undergo extremely slight electrostatic charging.
  • European Patent EP-A 1 128 713 discloses tiles made from highly compressed thermoplastic with a nonconductive support layer and a conductive wearing layer. A wearing surface of the wearing layer is provided with a securely adhering conductive substance.
  • the tiles described in that document have connecting elements in tongue-and-groove form. Only specialist workers can lay tiles of this type. The tongue-and-groove connection often tears, and in addition the tiles are complicated and expensive to produce.
  • Tiles for floor coverings are generally secured to one another by means of plug connections.
  • the joints which are present between the individual tiles are susceptible to dust and dirt. This can lead to the projections curving upward over the course of time. This makes the floor covering more difficult to drive on and reduces its service life, which is undesirable for economic and ecological reasons.
  • a further object of the present invention is to provide a covering surface which is produced using tiles which are easy to lay and which has a long service life.
  • the wearing layer of the tile according to the invention is polygonal in shape and is preferably square or hexagonal.
  • the wearing layer does not have either cutouts or projections. After the tiles according to the invention have been laid, neither cutouts nor projections are visible from above, since the tiles are mechanically secured by the support layer.
  • the floor covering has narrow joints between the individual tiles. The regular, preferably square pattern of these joints also allows simple welding, so that it is impossible for any dirt to adversely affect the floor covering.
  • the wearing layer is preferably electrically conductive.
  • the support layer of the tile according to the invention is of substantially the same size as the wearing layer and is preferably likewise polygonal. In its edge regions, the support layer has projections and mating cutouts. The edge region of the support layer has a width which corresponds to the length of the cutouts and projections. The projections are intended to engage in a positively locking manner in the cutouts in adjacent tiles.
  • the intermediate layer extends over at least two adjacent edge regions of the support layer and at least two further edge regions of the support layer are free of the intermediate layer.
  • this leads to those projections on the edge regions of the support layer over which the intermediate layer extends engaging in those cutouts in the edge regions of the support layer which are free of the intermediate layer.
  • a covering which is produced using the tiles according to the invention has a continuous intermediate layer, ensuring electrical conductivity over the entire area. Since the location of the mechanical connection is not at precisely the same point as the electrical connection, this means that slight local shifts in adjacent tiles do not lead to an interruption in the conductivity, and therefore there is a high degree of reliability with regard to the electrical conductivity.
  • the intermediate layer extends over at least two adjacent edge regions of the support layer and over the projections of the support layer of two further adjacent edge regions. The result of this is that the intermediate layer is doubled up in those regions in which the tiles are secured to one another. Therefore, a floor covering produced in this way satisfies the high demands imposed with regard to the electrical conductivity.
  • the tiles according to the invention can even be laid on uneven subfloors without the dissipation of the electrostatic charges being adversely affected.
  • the tiles according to the invention are laid without a fixed joint to the subfloor.
  • Production of the tiles according to the invention is very advantageous, since only the wearing layer has to satisfy the particular demands with regard to the electrical conductivity, the resistance to wear and the resistance to aggressive chemicals.
  • the intermediate layer has to be electrically conductive.
  • inexpensive materials such as for example reclaimed materials, can be used for the support layer.
  • the wearing layer of the tile according to the invention is preferably made from thermoplastic particles, generally chips, which are provided with a conductive coating before being pressed. During the pressing at elevated temperature, the plastic particles are subjected to considerable deformation together with the conductive coating, resulting in a homogeneous block which has uniformly distributed, thin conductive layers passing through it.
  • the wearing layer has a grid printed on its underside, increasing the conductivity between wearing layer and intermediate layer (cf. also EP 0 869 217).
  • the projections it is particularly advantageous for the projections to have a dovetail-like shape, since this makes the laying of the tiles to form a covering surface and also dismantling of such a covering surface particularly simple without the electrical conductivity between the tiles being adversely affected.
  • the dovetail-like cutouts may be either polygonal or undercut. In one embodiment, narrow and wide projections and undercuts alternate at regular intervals. The shape and width of the dovetails can be matched to the demands of the particular application; in particular, appropriate attention must be paid to the radii.
  • the electrical charging is preferably dissipated via the edges of the covering surface produced using the tiles according to the invention.
  • the intermediate layer of the tiles according to the invention is an electrically conductive sheet-like structure.
  • This may, for example, be a metal grid, a pattern of conductive fabric or copper strips, but may also be a conductive film or a conductive coating layer.
  • Polystyrene films with added carbon black and soft polyvinyl chloride films with added carbon black are particularly preferred.
  • the load-bearing capacity of the support layer is increased if the support layer has compression elasticity properties.
  • the support layer may be at least half made up of a polygonal structure, such as a honeycomb structure.
  • the recesses in the edge regions of the polygonal structures improve the ventilation of the subfloor, which is preferable in particular in moist environments.
  • the tile according to the invention is preferably produced in such a way that the intermediate layer is applied to the wearing layer which has been laid down. This can be effected either by applying the film or by applying a coating.
  • the support layer is applied, preferably by means of injection molding, to the intermediate layer which has been applied to the wearing layer.
  • FIG. 1 illustrates an overall view of the tile according to the invention from below
  • FIGS. 2 a and 2 b each illustrate diagrammatically an exploded view of the support layer, intermediate layer and wearing layer of the tile;

  • FIG. 7 diagrammatically illustrates the support layer from above
  • FIGS. 8 and 9 each illustrate an overall view of a preferred embodiment.
  • FIG. 1 illustrates the tile 1 from below, having an insulating support layer 2 , an electrically conductive intermediate layer 3 , and an electrically conductive wearing layer 4 .
  • the wearing layer 4 is made from a highly compressed thermoplastic. Of course, the wearing layer may also be made from other materials.
  • the intermediate layer 3 which lies between the support layer 2 and the wearing layer 4 is fixedly joined to both.
  • the support layer 2 has integrally formed projections 6 a , 6 b , 6 c and 6 d and cutouts 7 a , 7 b , 7 c and 7 d .
  • the projections 6 a , 6 b , 6 c and 6 d are intended to engage in a positively locking manner in the cutouts 7 c , 7 d , 7 a and 7 b of adjacent tiles.
  • the projections 6 a and 6 c are narrower than the projections 6 b and 6 d .
  • any desired width of the projections and cutouts is possible.
  • variants in which the projections and cutouts have the same width or the projections alternately have different widths are preferred.
  • the intermediate layer 3 extends over two adjacent edge regions 9 a and 9 b of the support layer.
  • the two further edge regions 9 c and 9 d of the support layer 2 which lie opposite the edge regions 9 a and 9 b and are likewise adjacent, are free of the intermediate layer.
  • the tile according to the invention is therefore configured in such a way that the projections 6 a and 6 b located in the edge regions 9 a and 9 b are intended to engage in the cutouts 7 c and 7 d of adjacent tiles, so that the intermediate layer extends continuously over the entire covering.
  • the mechanical connection between two tiles is not at the same location as the electrical connection. Therefore, slight shifts in tiles within the area of the covering do not lead to an interruption in the electrical conductivity.
  • FIG. 2 a diagrammatically illustrates the support layer 2 , the intermediate layer 3 and the wearing layer 4 which are intended to be fixedly joined to one another.
  • the intermediate layer 3 and the wearing layer 4 are of the same size and are applied one above the other over the entire surface.
  • FIG. 2 b diagrammatically illustrates the support layer 2 , the intermediate layer 3 and the wearing layer 4 which are intended to be fixedly joined to one another.
  • the intermediate layer 3 a has, in the edge regions 9 c ′ and 9 d ′, projections 6 c ′ and 6 d ′ which are intended to cover the projections 6 c and 6 d of the support layer 2 .
  • the wearing layer 4 , the intermediate layer 3 a and the support layer 2 are of substantially the same size.
  • FIG. 3 illustrates the tile 1 from above, with an insulating support layer 2 , an electrically conductive intermediate layer 3 and an electrically conductive wearing layer 4 .
  • the edge regions 9 c and 9 d are free of the intermediate layer.
  • FIG. 4 shows part of the tile according to the invention.
  • the intermediate layer 3 which has been applied to the wearing layer 4 extends over the edge region 9 a of the support layer 2 , while the edge region 9 c of the support layer 2 remains free of the intermediate layer.
  • the intermediate layer of the tiles according to the invention is an electrically conductive sheet-like structure.
  • This may, for example, be a metal grid, a pattern of conductive fabric or copper strips, but may also be a conductive film or a conductive coating layer.
  • Polystyrene films with added carbon black and soft polyvinyl chloride films with added carbon black are particularly preferred.
  • Polystyrene films can be made conductive by adding carbon black. These films preferably have a carbon black content of from 15 to 25%, preferably 18 to 22%. It is preferable to use polystyrene film or a PVC film with a thickness of 150 to 250 ⁇ m, preferably 200 to 250 ⁇ m. To produce these films, it is possible to use compounds in granule form, such as for example CABELEC 3896 produced by Cabot. Granules of this type have, inter alia, the following properties:
  • the film produced therefrom with a thickness of 200 ⁇ m, has a volume resistance determined in accordance with DIN 51953 of approx. 10 4 ⁇ .
  • a coating of this type may, for example, have the following compositions:
  • the graphite particles in the graphite suspensions have a grain size of between 1 ⁇ m and 100 ⁇ m, preferably from 1 ⁇ m to 30 ⁇ m. Suspensions incorporating graphite particles with a size of from 3 ⁇ m to 10 ⁇ m have proven particularly advantageous. For suspensions which contain carbon black, carbon black particles of large active surface area, preferably between 500 m 2 /g and 1500 m 2 /g, have proven advantageous.
  • the coating has to be applied to the wearing layer in such a way that it forms a cohesive layer with a thickness of a few micrometers.
  • FIG. 5 shows a diagrammatic view of the support layer 2 and the intermediate layer 3 .
  • the intermediate layer extends over the edge regions 9 a and 9 b of the support layer 2 , while the edge regions 9 c and 9 d of the support layer 2 remain free of the intermediate layer.
  • the load-bearing capacity of the support layer is increased if the support layer has compression elasticity properties.
  • the support layer may be at least half made up of a polygonal structure, such as a honeycomb structure. The recesses in the edge regions of the polygonal structures improve the ventilation of the subfloor, which is preferable in particular in moist environments.
  • the support layer is preferably made from a reclaimed product, for example having the following composition:

  • a tile over which a fork-lift truck drives should, for example, satisfy the following demands:
  • the force per bearing surface area is 2000 N.
  • 16 connections should be used on each side, meaning a combination of 8 projections and 8 cutouts on each side of the support layer of the tile according to the invention. If there is a smaller number of connections, the maximum load-bearing capacity is reduced accordingly.

  • the support layer 2 a is hexagonal in shape, i.e. has a honeycomb structure.
  • the hexagon is delimited by narrow joints 12 .
